Edible Uses
Edible Parts: Fruit; Oil.
Fruit - raw or cooked. Very rich in vitamin C (120mg per 100g) and vitamin A, they are too acid when raw for most people’s tastes, though most children seem to relish them. Used for making fruit juice, it is high in vitamins and has an attractive aroma. It is being increasingly used in making fruit juices, especially when mixed with other fruits, because of its reputed health benefits.
The fruits of some species and cultivars contain up to 9.2% oil. The fruit is very freely borne along the stems and is about 6 - 8mm in diameter. The fruit becomes less acid after a frost or if cooked. The fruit is ripe from late September and usually hangs on the plants all winter if not eaten by the birds. It is best used before any frosts since the taste and quality of frosted berries quickly deteriorates.
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Astringent; Cancer; Cardiac; Poultice; Tonic; Vermifuge.
The twigs and leaves contain 4 - 5% tannin. They are astringent and vermifuge. The tender branches and leaves contain bio-active substances which are used to produce an oil that is quite distinct from the oil produced from the fruit. Yields of around 3% of oil are obtained. This oil is used as an ointment for treating burns.
A high-quality medicinal oil is made from the fruit and used in the treatment of cardiac disorders, it is also said to be particularly effective when applied to the skin to heal burns, eczema and radiation injury, and is taken internally in the treatment of stomach and intestinal diseases. The fruit is astringent and used as a tonic. The freshly-pressed juice is used in the treatment of colds, febrile conditions, exhaustion etc.
The fruit is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavonoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers. The juice is also a component of many vitamin-rich medicaments and cosmetic preparations such as face-creams and toothpastes. A decoction of the fruit has been used as a wash to treat skin irritation and eruptions.
